QLC flash is tricky stuff to make and use, so here's a primer

QLC flash primer Quad-level cell (QLC) flash stores 4 bits per NAND cell and is very tricky stuff to use, far trickier than TLC (3 bits/cell) which is harder to user than 2 bits/cell MLC which, you guessed it, is more difficult to use than 1bit/cell SLC. Why is QLC the hardest of all to use? It is the slowest to read and write …

Good gravy, Toshiba QLC flash chips are getting closer

Backgrounder Toshiba is pushing flash chip capacity higher on two fronts: through, er, Through Silicon Vias (TSVs) and by increasing a cell's bit count to four. We covered the TSV notion here and now take a look at quadruple level cell (QLC) flash technology. Toshiba will present on this and TSVs in a keynote session at the August 8-11 …

Alphabetti spaghetti: SanDisk adds SLC cache to TLC SSD

Acronym alert: SanDisk has upgraded its Z400 PC SSD by changing it from an MLC drive to a TLC one with an SLC cache, doubling its capacity as well making it faster. The Z400 SSD used 15nm MLC (2 bits/cell) flash when it was introduced a year ago. SanDisk has kept the 15nm NAND but changed it to TLC (3bits/cell), upping its …

Storage with the speed of memory? XPoint, XPoint, that's our plan

Analysis Since the virtual dawn of computing, storage – where data puts its feet up when it's at home – has been massively slower than memory, where data puts on its trainers and goes for a quick run. That massive access speed gap has been getting narrower and narrower with each storage technology advance: paper tape, magnetic tape, …

Commodity flash just as good as enterprise drives, Google finds

If you're loading up a heap of flash drives for your data centre, don't bother with “enterprise-class” SLC (single level cell) technology, because cheaper MLC (multi-level cell) drives will do the job just as well. However, the data centre biz needs new techniques to predict drive failures, because the unrecoverable bit error …

Disk is dead, screeches Violin – and here's how it might happen

Analysis And in a flash, disk is dead. Well, actually, not that fast. But flash array flogger Violin Memory is convinced disk is dying in the data centre, killed by a series of NAND acronyms: 2D MLC, 3D TLC and, the final blow, 3D QLC. Is this view realistic? Even remotely realistic? It starts from a pair of observations by Violin …

Flash is fallible. But you'd rather have an AFA than spinning rust

We tend to think of flash as a solid-state disk – like spinning rust, only more expensive, consuming less power, and much, much faster. And yes, it is true that you can use it like that, but there is a lot more that flash can offer if you start to take into consideration what makes flash different in the first place. Simply …
